CVE-2026-76235

The login page handler in cockpit-ws (the Cockpit web service) leaks a heap allocation on every unauthenticated request carrying a CockpitLang cookie, in the send_login_html function. An unauthenticated remote attacker can repeatedly trigger this to exhaust host memory and cause denial of service...

CVE-2026-76235 Cockpit-ws: cockpit: cockpit-ws: unauthenticated remote memory leak via cockpitlang cookie in send_login_html

A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service...

CVE-2026-50142

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.0, a crafted HEIF sequence accepted by heifcontextreadfrommemory with the msf1 sequence brand can cause unbounded heap allocation. In libheif/sequences/seqboxes.cc, Boxstsz::parse applies maxsequenceframes only to...

CVE-2026-50142 libheif: unbounded heap allocation in HEIF sequence parser (stsz fixed-size mode missing bound check)

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.0, a crafted HEIF sequence accepted by heifcontextreadfrommemory with the msf1 sequence brand can cause unbounded heap allocation.

CVE-2026-50142

libheif 1.19.0–1.23.0 is vulnerable to denial-of-service via crafted HEIF sequences: Box_stsz::parse() omits bound checks in fixed-size mode, and Track::load() 32-bit arithmetic wraparound bypasses consistency checks, allowing multi-gigabyte allocations. No in-the-wild exploitation reported. Fixe...

CVE-2026-72202

A flaw was found in the Linux kernel's NTFS filesystem driver. When calculating free clusters or Master File Table MFT records, a temporary state object is allocated on the heap. If this allocation fails, processes waiting for these counts can become unresponsive, leading to a denial of service D...
